Below the effect of the control method of washing of the washing machine of structure describes to having as above.
Fig. 5 A to Fig. 5 E is the flow chart of the washing control sequence of operation of the washing machine that the present invention relates to of expression.S among Fig. 5 A to Fig. 5 E represents step (Step).
At first connect the power supply of washing machine, the alternating voltage that is provided by AC power end 100 promptly is applied in the primary side of the negative boosting transformer 51 of power subsystem 50.
At this moment, the reduce pressure alternating voltage of the defined that becomes to be fit to circuit working of the alternating voltage that described negative boosting transformer 51 will put on primary side is again to bridge rectifier 52 outputs of secondary side.Described bridge rectifier 52 will be depressurized the DC voltage of the ac voltage rectifier one-tenth regulation of transformer 51 decompressions.
Be contained in by the fluctuation composition in the DC voltage of described bridge rectifier 52 rectifications, C1 filters by filter condenser, output 12V (V
DD) the TRIAC driving voltage, be transformed into constant positive voltage (V by the DC voltage of described filter condenser C1 filtering by voltage stabilizing element 53 and filter condenser C2
CC: 5V), the driving voltage of the control module 60 of output 5V.
Therefore, step S1 will make the washing machine initialization by the driving voltage of the 5V of described voltage stabilizing element 53 outputs to control module 60 inputs.
Then, the user drops into washings in drench pit 7, by the desirable wash conditions of running operating unit 55 input (washing kind, wash time, to water washing etc.), then opens not shown running switch.Step S2 to water-supply valve driver element 80 output high-level control signal, detects the washings amount necessary washings put into described drench pit 7 in so that inject by lead-out terminal 01 in sink 9.
Described water-supply valve driver element 80 is to the high-level control signal of phase inverter (INV1) input by lead-out terminal 01 output of control module 60, after oppositely becoming the low level control signal, apply by the control utmost point of resistance R 1 again to TRIAC (TRIAC1).
Thus, between the control utmost point of described TRIAC (TRIAC1) and main electrode, produce voltage difference, connect TRIAC (TRIAC1), apply alternating voltage from AC power end 100 to water-supply valve 15, owing to opened described water-supply valve 15, by water hose 13, inject in the sink 9 by washings such as the warm water of hose 11 supply or cold water.
At this moment, step S3 detects by water level detecting unit 70 owing to open water level in the sink 9 that described water-supply valve 15 water fillings rise, and to control module 60 outputs.Described control module 60 is differentiated the bubble amount sensed water level (detecting optimum level of water, weak ' minimum ' water level of the washings amount that drops into) whether the water level that is detected by water level detecting unit 70 arrives prior setting.
According to the differentiation result of described step S3, when the water level that control module 60 is differentiated is not bubble amount sensed water level (during NO), then turn back to step S2, open water-supply valve 15 and continue water filling, repeat the later action of step S2, till arriving bubble amount sensed water level.When water level is bubble amount sensed water level (during YES), because must stop water filling, so in step S4, control module 60 to water-supply valve driver element 80 output low level control signals, is closed water-supply valve 15 by lead-out terminal 01.
After washings arrived bubble amount sensed water level, in step S5, control module 60 was cut off the electricity supply and is closed motor 21 behind motor 21 power supplies and CD-ROM drive motor 21.
Even close described motor 21, because the effect of the revolving force that inertia produced of motor 21, impeller 27 is still rotating.In step S6, when bubble amount detection unit 65 detects the rotation of motors 21 inertia because the rotation number of the impeller that rotation produced 27 of reducer pulley 24, control module 60 will rotate number and compare with the standard rotation number of having set (judging the basic rotation number of the impeller of washing weight), judge the weight of washings with this.
After judging the weight of washings, control module 60 is according to the weight decision washings of washings, enter step S7 then, export high-level control signal by lead-out terminal 01 to water-supply valve driver element 80, open water-supply valve 15, in sink 9, inject washings so that press the water level that is determined.
After described water-supply valve 15 is opened, inject in sink 9 by water hose 13 by washings such as the warm water of hose 11 supply or cold water.At step S8, detect the water level that in sink 9, injects by water level detecting unit 70, differentiate the water level that whether has arrived control module 60 decisions.
According to the differentiation result of described step S8, when not being the decision water level (during NO), turn back to step S7, open water-supply valve 15 and continue to inject washings, and repeat the later action of step S7, when reaching the decision water level, end.When being the decision water level (during YES), because must stop water filling, so control module 60 is closed water-supply valve 15 by lead-out terminal 01 output low level control signal.
After washings arrived the decision water level, in step S9, control module 60 was alternately exported the right rotation of high level or the control signal of anticlockwise to motor drive unit 85 by lead-out terminal 02,03.
Therefore, described motor drive unit 85 will be imported to phase inverter (INV2, INV3) by the high-level control signal that the lead-out terminal 02,03 of control module 60 is exported, after oppositely becoming the low level control signal, apply to the control utmost point of TRIAC (TRIAC2, TRIAC3) by resistance R 2, R3.
Thus, produce voltage difference between the control utmost point of described TRIAC (TRIAC2, TRIAC3) and main electrode, TRIAC (TRIAC2, TRIAC3) is connect is able to right rotation or anticlockwise.
Because the driving force that is produced that turns left and right of described motor 21 is delivered to decelerator 23 by belt 25, reducer pulley 24 begins to rotate, the impeller 27 that is connected with the axle 23a of decelerator 23 finally begins right the reverse, make washings form the current direction washings and exert pressure, carry out the washing procedure that separates attached to the dirt on the washings and impurity etc.
Next, in step S10, the wash time that reverses about the described impeller 27 of control module 60 calculating judged whether to have passed through four minutes, when not through four minutes (during NO), turned back to described step S9, repeated the later action of step S9.(during YES) enters step S11 when having passed through four minutes, and conductance detecting unit 75 detects through the washing agent injected volume after the washing in four minutes with because the conductance A of the washings that the contaminant capacity of washings changes, and exports to control module 60.
Then,, calculate the difference Z1 of the washings conductivity values X of conductance detected value A and initial feedwater,, whether differentiate described conduction rate variance Z1 greater than control module 60 preset standard conduction rate variance Z at step S13 at step S12
SAs conduction rate variance Z1 overgauge conduction rate variance Z
SThe time (during YES), enter step S14, carry out to set the washing procedure of wash time.
According to the judged result of described step S13, when conducting electricity rate variance Z1 less than standard conductive rate variance Z
SThe time (during NO), enter step S15, carry out washing procedure after adding 3 minutes on the wash time setting.
Whether at step S16, differentiating is that wash time ended last minute.When not being ends (during NO) last minute the time, carry out wash time by washing procedure in the time of conduction rate variance Z1 decision, repeat the action of step S16.When being ends (during YES) last minute the time, enter step S17, conductance detecting unit 75 detects the conductance B of sink 9 washed water that change in the washing procedure of ending last minute the time.
Step S18 calculates the difference Z2 of last minute the conductance detected value B conductance detected value A with through four minutes time of ending, and step S19 judges that described conduction rate variance Z2 is whether greater than by control module 60 preset standard conductance Zs.When conduction rate variance Z2 overgauge conduction rate variance Zs (during YES), enter step S20, append the washing procedure that carries out two minutes, thereafter,, inject and untie at the current of washing process around the washings of knot at step S21, washing procedure finishes.
According to the judged result of step S19, as conduction rate variance Z2 during less than standard conductive rate variance Zs (during NO), do not append and carry out washing procedure, enter described step S21, inject to untie and behind the current of the washings of knot, finish washing procedure at washing process.
Carry out washing procedure in the best wash time that conductance determined of the washings that in by washing procedure, change, thereafter enter step S22, control module 60 is exported high-level control signal by lead-out terminal 04 to draining valve driver element 90, so that the contaminated washings in the sink 9 are discharged.
